The warning/alarm information below defines each
warning/alarm condition, provides the probable cause for
the condition, and details a remedy or troubleshooting
procedure.
WARNING 1, 10 Volts low
The control card voltage is below 10 V from terminal 50.
Remove some of the load from terminal 50, as the 10 V
supply is overloaded. Max. 15 mA or minimum 590
This condition can be caused by a short in a connected
potentiometer or improper wiring of the potentiometer.
Troubleshooting
Remove the wiring from terminal 50. If the warning clears,
the problem is with the customer wiring. If the warning
does not clear, replace the control card.

109 terminals 1, 3, 5 for signals, terminals 2, 4, 6
common).
Check that the frequency converter programming
and switch settings match the analog signal type.
Perform Input Terminal Signal Test.
